JohanHappy Johan Santana Day! (a.k.a. The Great Santana) What, don't you say that every time Mets Ace Johan Santana is scheduled to take the mound? Before he does, let's take a look at the state of the Mets rotation.This time through the rotation the Mets will be showcasing Johan Santana, Mike Pelfrey, Tim Redding, John Maine and Livan Hernandez.Let's see how they've done this year and what we might expect from  them this week:Johan Santana (5-2):Santana won the NL Pitcher of the Month Award in April and is well on his way to another Cy Young caliber season. In his last start, Santana allowed six runs, four earned on 11 hits against the San Francisco Giants but still managed to get a Win thanks to some great hitting by the Mets.As fangraphs.com points out here,
Santana is primed for a huge season. In 39.2 innings this season, Santana has punched out a jaw-dropping 54 batters (12.25 K/9), which is the highest rate of his career. His FIP sits at a microscopic 2.03, and he has compiled 1.7 WAR already.
In his last start against the Red Sox, Santana allowed one run on 7 hits in 5 innings.Mike Pelfrey (4-1):Mike PelfreyPelfrey had a case of the Yips last week. He allowed 2 runs on 6 hits against the San Francisco Giants but suffered his first loss of the season as the Mets were unable to score on Matt Cain and the Giants bullpen.Pelfrey is sporting a 1.54 WHIP, .286 BABIP, and a 5.23 FIP. Most striking is his 0.65 K/BB ratio, the worst in his career. However, his GB/FB ratio stands at 1.80, the best of his career.Tim ReddingTim Redding (0-0):Redding allowed two runs on 2 hits while walking four and striking out four in six innings against the Los Angeles Dodgers. Nonetheless, the Mets made 5 errors and left 11 on base, and in the 11th, had probably one of the worse innings in baseball this year (Glad I went to bed after the 10th).I won't bore you with any stats, since one game is not enough to go off of.John MaineJohn Maine (3-3):Maine allowed five runs (four earned) on eight hits while walking three and striking out three in 5 1/3 innings against the Los Angeles Dodgers. Maine flirted with disaster the whole night but hung a slider to Casey Blake for a three run home run.Maine is sporting a 1.42 WHIP, .260 BABIP and a 4.83 FIP. His career best GB/FB ration is 0.80 (2006) but stands at 0.91 this year. Also, Maine's LD ratio is at 22.5%, the highest of his career.Livan HernandezLivan Hernandez (3-1):Livan allowed one run on seven hits while walking one and striking out two in seven innings against the Los Angeles Dodgers. Livan was wonderful, but the offense failed him as they left nine on base and couldn't capitalize when they needed to.Livan is sporting a 1.47 WHIP, .316 BABIP and a 4.65 FIP. In his last start against the Washington Nationals last year, Livan allowed six runs giving up 10 hits in six innings.The Mets need the rotation to continue to give the team quality starts, especially with the bats slumping. If the Mets are able to take 2 of 3 from the Boston Red Sox, they'll come back with a 23-20 record and would've gone 6-5 on the west to east trip. Let's Go Mets!P.S. I'd love some feedback, especially about what's missing from this post. Thanks.
