Red Sox prospect Rubby De La Rosa is in pitching purgatory. Fully healthy since late in the 2012 season, the right-hander with an electric fastball is nowhere to be found on 25-man roster projections. I don’t expect this to last long since De La Rosa has the arsenal to force his way onto the staff. For now, however, the Dominican will be forced to wait his turn.

It seems like an eternity ago, but De La Rosa’s debut in Dodger blue was impressive. His 3.55 xFIP in 60 2/3 innings included ratios of nearly a strikeout per inning and ground ball rate approaching 50-percent. He walked too many batters — A carry over from Double-A, but De La Rosa was only 22. Time and ability was on his side. Read the rest of this entry »

It’s important, of course, to acknowledge always that front offices — especially the sort which have a reputation for embracing all manner of analysis — that they might possess certain information to which we, baseball’s laypeople, are not privy. To whatever degree that might be the case, however, it’s difficult to imagine what information precisely the Red Sox might have with regard to Jonny Gomes, whom the club signed to a two-year, $10 million contract this offseason and intends, it seems, to deploy as their starting left fielder. While the bar is rather low for Gomes to earn his money, Dan Szymborski’s math computer suggests that Gomes’ odds of producing like an average major-leaguer aren’t excellent.

I asked Szymborski about the Gomes projection — and, in particular, to what degree it might account for platoon splits (Gomes having a reputation for possessing a large-ish one). To which question Szymborski replied: “ZiPS only knows past usage.” To that point, we ought to consider this when considering Gomes’s rather successful 2012 season: about 59% of Gomes’s plate appearances in 2012 were against left-handed pitchers. Meanwhile, only one-third of his plate appearances between 2009 and -11 were against lefties.

In 2008, Mike Aviles was a 27-year-old minor league infielder in the Royals’ system who had to get a lucky break for the club to play him over this historically terrible Tony Pena, Jr. Yesterday, the soon-to-be 32-year-old Aviles got his first multi-year, guaranteed deal with Cleveland, which bought out his last two years of arbitration for $6 million and a club option for 2015. It has been quite the odyssey for Aviles, who was drafted by the Royals seventh round in 2003, in large part because he would sign for a $1,000 signing bonus (David Glass is great, isn’t he? Let’s give a hand to David Glass, folks!), has seen himself passed over for the likes of the aforementioned Pena, Yuniesky Betancourt and Chris Getz, and was traded twice this winter, including once for a manager.

Despite all that, Aviles has shown himself to be a useful player — and while this contract is hardly huge in itself — it might have interesting implications for how Cleveland’s roster might shake out in the near future.

Henry Owens‘ final start of 2012 was a scoreless one. In five innings, the 20-year-old struck out four, allowed eight base runners and a number of hard-hit balls. Minus a run or two, it was a typical start for the left-hander.

This off-season, the chatter on Owens has been less polarizing than expected. Yes, a 3.49 FIP and 11.51 K/9 is impressive. However, his 4.16 BB/9, .350 BABIP and low ground-ball percentage are all troublesome. Owens presented similar to his stat line during a September scouting trip to Greenville, South Carolina.

There are a bunch of things we know to be true about Aaron Cook, or at least things we have no reason to question. Aaron Cook played for the Rockies, and he recently played for the Red Sox. More recently he was signed by the Phillies. He is a man, and he is a man of more than 30 years, and he is a man who grows reddish facial hair when he wants to, and even when he doesn’t. Aaron Cook knows many things about the game of baseball. Last season, Cook posted one of the lowest strikeout rates ever.

Strikeouts, of course, have never been a big part of Aaron Cook’s game — when he’s right, he gets a bunch of grounders. When he’s wrong, he also gets a bunch of grounders, but the overall results of everything are worse. Cook, in 2012, didn’t post the lowest strikeout rate in baseball history. He did post the lowest strikeout rate since the strike, at 4.9% of all batters. There were 411 batters, and 20 of those batters struck out. When Cook was in triple-A in 2012, there were 153 batters, and 16 of those batters struck out, so this was predictable to some extent.

Only 27 players have hit 100 or more homers and stolen 400 or more bases in their career. Eleven of them are in the Baseball Hall of Fame, and four others can reasonably be expected to reach Cooperstown. But there are some names on the list you wouldn’t pull off the top of your head. Tommy Harper? Yep, he’s one of those names. He is also a possessor of that rare feat: the Random Career Year.

At the end of last May, Phil Dumatrait announced his retirement from professional baseball. It was an announcement that went largely unnoticed — note the three retweets — and that makes sense, because Dumatrait hadn’t pitched in 2012, and for his career he threw just 151 major-league innings over parts of four seasons. Many of them were not good innings, and while there are the usual qualifiers about how Dumatrait was one of the very best pitchers in the entire world, relative to his big-league peer group, he was lacking a certain something. “Ability to have consistent success,” is what he was lacking.

Dumatrait, like all professional ballplayers, once had a lot of promise. Dumatrait, unlike all professional ballplayers, was selected as early as in the first round in 2000. In fairness, that wasn’t much of a round — the two guys selected before Dumatrait have been worth negative WAR, and the six guys selected after Dumatrait fell short of the bigs — but Dumatrait found his way to prospect lists. According to Baseball America, he was seventh in the Red Sox’s system before 2002. He was fifth in the same system the next year, and the year after that, he was sixth in the Reds’ system, one behind Joey Votto. Phil Dumatrait looked like he could be something, for a while. And, ultimately, he was a big-leaguer, if a relatively unsuccessful one.

Even More Javier Vazquez Baseball Coverage, Crazy!
Since last week’s update of the Puerto Rican League leaderboards, former major-league pitcher and potentially-again major-league pitcher Javier Vazquez has made another start (his fifth) for the Leones of Ponce — in which start Vazquez posted the following line (box): 6.0 IP, 25 TBF 7 K, 3 BB, 1 HR, 4:6 GO:AO. The performance further increased the right-hander’s lead over the league’s other starting pitchers, per the regressed pitching metric SCOUT- (below).

Armed with a new measure for offensive volatility (VOL), I wanted to revisit research I conducted  last year about the value of a consistent offense.

In general, the literature has suggested if you’re comparing two similar offenses, the more consistent offense is preferable throughout the season. The reason has to do with the potential advantages a team can gain when they don’t “waste runs” in blow-out victories. The more evenly a team can distribute their runs, the better than chances of winning more games.

I decided to take my new volatility (VOL) metric and apply it to team-level offense to see if it conformed to this general consensus*.

Kansas City Sign Chavez, Tejada
The Kansas City Royals have signed outfielder Endy Chavez and infielder Miguel Tejada to minor-league deals, reports MLB.com’s AJ Cassavell. The latter will become an MLB deal worth $1.1 million, according to Dionisio Soldevila of ESPN Deportes (with credit to MLB Trade Rumors’ Edward Creech for collecting same information). Tejada, who enters his age-39 season, has been worth 43.8 WAR over his career, although only about one of those wins has come over the previous three seasons.
