For whatever reason, the Indians pitcher said he started to be all over the place with his mechanics, and had to start from scratch.
"It's been taking time because my mechanics got so bad," Jimenez said.
Three starts ago against the Rangers, Jimenez pitched a gem. He held Texas to two hits over seven innings, and he had six strikeouts. In his next start against Boston, though, he got hit for seven runs in only 4 1/3 innings.
"Ubaldo continues to be inconsistent," said Indians general manager Chris Antonetti. "His commitment hasn't wavered. He's worked tirelessly to solidify his delivery mechanics. It just hasn't clicked consistently every five days."
Jimenez, who is 5-4 with a 5.09 ERA, said he's improving every day. He's been working with pitching coach Scott Radinsky on a regular basis, and he said he's starting to feel comfortable with his new mechanics.
"I'm pretty close," Jimenez said. "I'm not going to say that I'm one pitch away or one game away from putting everything together, but I'm getting better and better."
