The Good and The Bad of ’09: Boston

Over the next few weeks, we’re going to take a look at a minimum of two players for each MLB club: One player who exceeded expectations in 2009 and one player that failed to reach his potential. Today, we’re looking at the Boston Red Sox club that finished second overall in the American League East division with a record of 95-67. The organization claimed the Wild Card title but was eliminated in the American League Division Series. As a team, the Red Sox posted a Win Probability Added (WPA) of 4.01, seventh overall in the Majors and third in the AL.

The Good: Jon Lester, LHP
A lot of people felt that Lester peaked in his first full season in the Majors in 2008. A lot of people were wrong. The lefty, at the age of 25, became one of the top hurlers in baseball. He allowed 186 hits in 203.1 innings while striking out 225 batters (9.96 K/9). Lester also posted a nice walk rate at 2.83 BB/9. His fastball velocity increased 1.5 mph over 2008 but it took a step back value wise from 0.82 to 0.25 wFB/C. However, each one of his secondary pitches (cutter, curve, change) improved. Lester was worth 6.2 wins above replacement in 2009, up from 5.1 in 2008.

What’s important for fantasy owners to acknowledge is that he’s proven to be durable – especially considering that he’s coming back from cancer. All his statistics also point to a legitimate improvement in numerous areas, which limits the likelihood of a fluke season. Lester finished fifth in the Majors in strikeouts and he plays on a club that will give him plenty of opportunities to be awarded wins.

The Bad: Daisuke Matsuzaka, RHP
Matsuzaka looked like a stud after his first MLB campaign in 2007; He then won 18 games with just three losses and he posted a strikeout rate of 8.27 K/9 in his sophomore year. There were some red flags, though, such as the walk rate of 5.05 BB/9 and the significant ERA/FIP gap. Even so, Matsuzaka was worth 3.3 wins above replacement in ’08 and fans expected more in ’09. No one expected him to be worth just half a win above replacement, and no one expected Matsuzaka to make just 12 starts. Unfortunately, he was also extremely homer prone (1.52 HR/9), he allowed a lot of line drives (23%) and all of his pitches decreased in effectiveness.

Matsuzaka will enter the 2010 season with a wait-and-see label. The wild-card has a chance to be a dominating pitcher again if he can harness the command of his fastball and slider. His health will also play a huge part in his potential success. At just 29 years of age, Matsuzaka has the potential to provide innings, strikeouts and wins. You will have to accept a certain number of walks and homers, though.
