Ortiz looks to win his fourth straight start as the Braves resume a four-game series with the Philadelphia Phillies at Turner Field.
Coming off his career year, the veteran right-hander began this season 2-3 with a 5.61 ERA in his first five outings.
However, Ortiz has gone 4-1 with a 2.41 ERA in his last six starts, including a sparkling 3-0 with a 1.17 ERA in his last three.
“There are some years when I come out of spring training where I feel that I’m not throwing the way that I want to and it carries over to the start of the season,” said Ortiz after allowing two runs and seven hits over seven innings of an 8-2 win over Montreal on Monday.
“That’s the way it was this year.”
Ortiz will try to help the Braves rebound from a 9-1 loss to the Phillies on Friday.
Lieberthal’s homer and RBI single improved his career average at Turner Field to .374 (61-for-163) with 11 homers and 51 RBIs.
“I do see the ball well here,” Lieberthal said after raising his season average seven points to .231.
“Last night, I felt good. Hopefully, I have something.”
