The last few weeks have been full of frustration for Red Sox left-hander Eduardo Rodriguez. In four starts since coming off the disabled list, he's 1-2 with a 6.97 ERA.
Rodriguez will try to change that on Wednesday when the Red Sox and White Sox, who will start Jose Quintana, square off at Fenway Park.
Since his start on Thursday against the Orioles, in which he allowed five runs on eight hits in 4 1/3 innings for the loss, Rodriguez has gone back to his old delivery.
"It's a natural delivery to him. He's gotten back into it quickly and has a better rhythm and energy in his delivery," Red Sox pitching coach Carl Willis said. "We are hoping that along with that better rhythm and energy comes better command."
While Rodriguez has maintained consistent fastball velocity, topping out at 96 mph, he's lacked the same kind of conviction in his secondary pitches.
"He has confidence in his changeup, just not as much in his breaking pitches," Willis said. "We've made a little bit of an adjustment with that in which he has taken to this past week. Because of that, I think we'll see a lot more effectiveness."
Quintana's also had his fair share of frustration, but for a completely different reason. He's gone 0-6 with a 3.86 ERA over his last seven starts, receiving a total of five runs of support, after going 5-1 with a 1.38 ERA over his first seven starts.
The left-hander allowed two runs on seven hits in 7 2/3 innings on Friday against the Indians for the no-decision. It broke a streak of six straight losses.
"You know, I hope that it changes," said Quintana after his last start. "I'll just try to get it going next start. It's not for me, it's for the team. Just here to try to do my job and keep the games close."
