Does Jeff Francis fit with Cincinnati?

On the surface, the Reds signing of Jeff Francis to a minor-league contract seems like no-news news. However, I think he has a chance to play an important role on a team that should probably be considered the favorite in the National League Central.

Ok. A pitcher who went 6-16 with a 4.82 ERA and only 4.5 K/9 isn't generally much in demand, and Francis is several years and a major injury removed from his time as a promising young pitcher. The ninth pick in the 2002 draft, Francis rose quickly through the Colorado Rockies organization. Before the 2005 season, Baseball America ranked him the #23 prospect in baseball. In 2006 and 2007, he went 30-20. His ERA was 4.19, a number that might otherwise be mediocre but in Coors Field was a 116 ERA+. In 2007, he struck out 165 in 215.1 innings, and helped the Rockies reach their first World Series. Going into 2008, Francis's age-27 season, things looked good for both player and team.

Of course, these things don't always work out - Francis was experiencing shoulder soreness that caused him to be ineffective in 2008. The injury was determined to be an injured tendon in his biceps, and he was shut down after 21 starts. He attempted to rehab, but to no avail, and opted for shoulder surgery in February 2009, which shut him down for the next 15 months. Upon his return to the Rockies in May 2010, his fastball's velocity had lost about 4 mph, and he was generally ineffective all season. The Rockies cut ties with their former top prospect and Francis signed a one-year contract with the traditionally bottom-feeding Kansas City Royals for 2011.

In 2011, Francis wasn't especially good, but there are some positives, and some reason to think he could be a good signing for the Reds. First of all, while his 4.82 ERA is unsightly, his 4.10 FIP and 4.23 xFIP show that his peripherals are sometimes better than results. This is the second consecutive year Francis has underperformed what his statistics would predict, so it's important to determine whether Francis has been unlucky and should be expected to improve, or if he's just an AJ Burnett-corollary type, who consistently underachieves. That's not easy to do.

While his early-career ERA was generally in line with his FIP and other predictors, Francis is a totally different pitcher now, with a fastball that tops out at about 85. To compensate for his loss in velocity and declining strikeout rate, Francis has thrown more ground balls the last two seasons. Unfortunatly, he's been doing that in front of some pretty poor defenses - the Royals were 24th in baseball with a defensive efficiency(DE) of .701, and Francis ended up with a .316 BABIP. The Cincinnati Reds were 3rd in baseball and best in the National League with a .718 DE. That difference makes an especially big difference to a pitcher like Francis, who doesn't strike many batters out.

On the other hand, in his second year back from his injury, Francis's fastball actually lost velocity from 2010. Also, after an extremely effective July where he did everything well, he pitched very poorly the rest of the year. Whether this was fatigue or simply a regression to his actual ability remains to be answered. It's important to keep in mind, though, that he was at 135 IP by the end of July - he last reached that number in 2008, and he last reached it while healthy in 2007. If this was a case of fatigue, it was certainly understandable.

Something else to note - Francis allowed home runs on only 8.5% of his fly balls last year, despite a relatively low amount of infield flies, as Ryan Campbell of FanGraphs told us last week. That's not a good sign going into the Great American Ballpark, one of the best home run parks in baseball.

Even so, slightly worse luck on keeping fly balls in the park would be evened out by the fact playing in front of Cincinnati's defense will mean less people  are on base when those home runs are hit. He also will be facing pitchers instead of designated hitters this year, so if his durability and velocity come back to his previous numbers a bit more, he should be able to post a strikeout rate in the mid-5's, a number that should help bring keep his ERA in the low 4's.

Does that fit with Cincinnati? Sure, "you can never have enough pitching" as the old saying goes. Still, the Reds have Mat Latos and Johnny Cueto entrenched, can probably expect some sort of revival from the previously consistent Bronson Arroyo, and after that have Homer Bailey, Mike Leake and Aroldis Chapman. Of those three, Leake has more than earned the right to start. He wasn't as hyped as the other two, but as a first round draft pick who went straight to the majors, improved in every conceivable way in 2011, and is still only 24, why wouldn't they just pen him into the rotation?

Chapman, by contrast, has only made three professional starts, all in the minor leagues. The Reds say they are committed to him as a starter, and with his talent, they should be. Relievers are always available - the Reds owe it to themselves to give someone with Chapman's upside a chance to be as valuable as possible. What's the harm of letting him start the year at Triple-A though? With six other established starters in a weak division, the Reds are already poised to compete. No reason to throw Chapman into the fray before he's ready and risk both his confidence and their chances at the division.

That's where Francis fits in. Appearing as the 7th starter at first glance, he's more MLB-ready than Chapman. Quick question - do you expect all five of those starters, particularly Cueto and Bailey, to go the entire season without injury? That's unrealistic of any staff, even one comprised entirely of starters with a good health history. Francis could have significant value as a "swingman" type, starting out as a left-handed long reliever who is ready to move into the rotation if (when) one of the starters gets hurt. Much better him than trying to coordinate calling up Chapman the first time an injury strikes.

For $1.5 million for a pitcher with Francis's experience and likelihood of success, that seems like a sensible investment for the Reds.

The Excellence of the Pittsburgh Defense

Well when you start with James Harrison and Troy Polamalu, excellence really should come as no surpr....

Wait, what? This is a baseball blog? And we're talking about the defense of the Pittsburgh Pirates??

At the All-Star break, the Pirates find themselves one game out of first place in the National League Central. This is a major surprise, since the last time the Pirates had even a winning record was 1992. The Pirates have been better in every facet of the game this year than last, but their most notable improvement has been in the run prevention category. The previous four seasons, the Pirates had finished in the bottom 3 in the league in runs allowed - in 2011, they rank 4th. Usually extreme leaps in run prevention are directly related to improved pitching, but in this case, the usual pitching numbers don't show much difference in quality:

-In 2007, the Pirates ranked 14th in runs allowed, 11th in the NL in K/BB ratio, and allowed 1.2 HR/9 - slightly worse than the league average of 1.0.
-In 2008, they ranked 16th in runs allowed, 16th in K/BB, and allowed 1.1 HR/9 (league average 1.0).
-In 2009, they ranked 14th in runs allowed, 15th in K/BB, and allowed 1.0 HR/9 (same as league average)
-Last year, 16th in runs allowed, 16th in K/BB, and allowed 1.1 HR/9 (league average was .9)
-This year, they are 4th in runs allowed, 15th in K/BB, .9 HR/9 (same as league average).

So, compared to last year, part of their improvement comes from allowing home runs at closer to the league average rate, but more of it comes from turning balls into play into outs:

2007: .685 Defensive Efficiency/ 15th in NL
2008: .689 DE/ 15th
2009: .700 DE/ 15th
20101' 689 DE/ 16th
2011: .716 DE/5th

That improvement can't be understated. Behind a pitching staff that strikes out fewer batters than any other NL team, the Pirates are turning 4% more balls into outs. Striking out only 6.2 per nine, to get those other 21 outs, Pirates pitchers face 29.2 batters rather than 30.4. Over the course of the season, this means they would pitch to 192 fewer batters.

Check out the effect this has had on some of the Pirates' starting pitchers:

Charlie Morton:
2010: 2-12, 7.57 ERA, 6.7 K/9, 2.9 BB/9, 1.8 HR/9, .357 BABIP
2011: 7-5. 3.80 ERA, 5.3 K/9, 3.5 BB/9, 0.3 HR/9. .316 BABIP

Morton's improvement has much to do with the extreme drop in home run rate - an improvement many attribute directly to pitching coach Ray Searange, who noticed that Morton was more effective with a lower release point. This emphasized the natural sink on his 95 mile per hour fastball, and has produced a ton of ground balls, and that's where the improvement in Pittsburgh's defense has made Morton's statistical improvement even more striking.

Paul Maholm
2010: 9-15. 5.10 ERA, 5.0 K/9, 3.0 BB/9, 0.7 HR/9, .327 BABIP
2011: 6-9, 2.98 ERA, 5.6 K/9, 3.1 BB/9, 0.5 HR/9, .252 BABIP

Maholm has only one previous season (2008) in his career with a BABIP under .300. Not coincidentally, it was the only season in his career with an ERA under 4.00.

Jeff Karstens
2010: 3-10, 4.92 ERA, 5.3 K/9, 2.0 BB/9, 1.5 HR/9. .309 BABIP
2011: 7-4, 2.55 ERA, 5.3 K/9, 1.7 BB/9, 1.6 HR/9, .240 BABIP

Karstens is the most striking example of the assistance the Pittsburgh defense is providing to its mediocre pitchers. Last year Karstens allowed too many homers and struck out not enough batters. This year, he's doing the same thing and has cut his ERA in half. Karstens is having one of those years which, if the Pirates were in their normal position 20 games under .500, they'd probably trade him to a contender - this might be the best half-season Karstens ever has, his value will never be higher. A .240 BABIP isn't sustainable, and other than a slightly better walk rate, Karstens is the pitcher he's always been. I'd expect his ERA to be in the 3.85-4.15 range in the second half.


There are several reasons for the improved Pirate defense. The first is the wonderfully fantastic Andrew McCutchen, leading National League CF with an 8.3 UZR. This was a huge improvement over his performance in the second half last year, and an even bigger improvement over Jose Tabata, a more natural corner outfielder who was overmatched in center. Another big improvement has been at SS, where Ronny Cedeno has a 4.2 UZR, following his -3.6 last year. Cedeno isn't much of a hitter, so his defense needs to carry his bat for him to be worth his playing time. This year it has done so. At 3B, it's been addition by subtraction. Pedro Alvarez (-6.2 in 2010, -2.3 so far in 2011) was injured, and replaced by a combination of Brandon Wood and Josh Harrison (4.2 UZR combined). Wood and Harrison can't hit though - Alvarez can (at least he did last year, and in the minors). The defensive disadvantage with Alvarez in the lineup is more than made up for by his superior bat.

Is the defensive improvement sustainable, or just a fluke? Mostly sustainable I think. The outfield defense with McCutchen and Tabata can cover a lot of ground. The infield defense may take a small step back (Alvarez returning, Cedeno regressing), but should still be above average.

Some credit is due to Clint Hurdle, as well. He's unafraid to use defensive replacements, and his Rockies teams usually had above average defenses despite playing in spacious Coors Field. It seems possible he and his staff are doing a good job positioning their fielders. If he keeps the Pirates in the race all year, he should run away with the Manager of the Year award.
