ALL STATS IN TABLES ARE AS OF JULY 1, 2009.
In my Top 41 before the season, I wrote:
Dr. Pangloss Says: Parnell's power arm gives him a chance to make the Mets out of spring training as an impact reliever late in games.
On the Flipside: Parnell's command issues limit his ceiling and lessen his chances of becoming an MLB starting pitcher.
Indeed, on the strength of his power arm, he did break camp with the Mets and his command issues have limited his effectiveness. Parnell is a useful piece of an MLB bullpen. That's important, but it hardly makes him untouchable if the Mets are looking to deal this summer. His strikeout rate (7.42/9) is a little above average, but his walk rate of 4.64 is awfully high, but not so out of line with his minor league numbers.
The Mets have passed over Kunz again and again for big league bullpen openings. The issues for Kunz have remained the same since the Mets drafted him in the supplemental first round in 2007: left handed hitters and commanding his pitches. He still struggles with both. Check that nearly 1:1 k:BB rate. Scouts see him as no more than another middle reliever these days.
Numerically, there's a lot to like about Rustich. He's striking out a batter an inning, walking under three per nine which leads to a K/BB above three and he never gives up homers. He throws hard and has a good slider. The only problem is that he can't stay healthy. In late June, he missed time with a blister problem, only his most recent in a long string of maladies. What exactly the Mets have in the big Bruin will remains a little hazy because he's missed so much time, but his last two outings have come out of the bullpen. Perhaps he has a future like Bobby Parnell's as a hard-throwing middle reliever.
Advanced to the Florida State League after a punchless debut in the New York Penn League with Brookly, Davis walked more and belted a few more extra base hits with St. Lucie. In particular, Davis got hot in June (.319/.418/.638 in 47 AB) proving to the Mets that he was done with A-ball. His early AA performance leaves room for optimism as he's hitting home runs and terrorizing righties while against lefties in AA (.200/.310/.240 in 25 AB) after not hitting much against them in the FSL either. A good defender and athelete around the bag, Davis now looks like a big leaguer. To make a difference, he'll need to keep improving offensively and learn to hit something else besides a fastball from a righthander.
Rodriguez has not appeared in a minor league game all year. Baseball America recently reported that the Mets placed him on their suspended list. That fact alone pushes him down below guys who are playing.
