4-5, 94 1/3 IP, 82 H, 61 R, 50 ER, 49 BB, 82 K, 10 HRA, 4.77 ERA, 1.39 WHIP
1-1, 17 2/3 IP, 17 H, 8 R, 8 ER, 10 BB, 9 K, 2 HRA, 4.07 ERA, 1.53 WHIP
Those two lines are both for the same pitcher, Ubaldo Jimenez. The first line is his numbers in games caught by Yorvit Torrealba, the second line is his numbers in games caught by Chris Iannetta. We are constantly being told by "the powers that be" that Torrealba is in there because of his excellent mentoring of our Latin pitchers.
With Ubaldo at least, there seems to be no big difference between his performance with Torrealba and Iannetta behind the plate. His walk and strikeout numbers are a little better with Torrealba, but his ERA is nearly a full run lower with Iannetta behind the dish. So, it doesn't seem to matter to Ubaldo who his catcher is. Franklin Morales, however, is a different story.
With Torrealba: 2-3, 41 1/3 IP, 37 H, 16 R, 16 ER, 23 BB, 22 K, 1 HRA, 3.48 ERA, 1.45 WHIP
With Iannetta: 2-1, 18 IP, 20 H, 16 R, 16 ER, 8 BB, 9 K, 2 HRA, 8.00 ERA, 1.56 WHIP
Morales, unlike Ubaldo, seems to actually benefit from having Torrealba catch him. His ERA more than doubles with Iannetta behind the plate. But Frankie's in the minors now, so if you look at the numbers the club currently has no excuse for keeping Iannetta on the bench. If/when Franklin comes back, though, get Yorvit behind the plate when Morales is on the mound.
