Masterson has been moved to the bullpen, MLB.com reports. Manager Mike Matheny has yet to name a starter for Thursday's opener against Milwaukee, but he has ruled Masterson out as an option, meaning it will be either Marco Gonzalez or Tyler Lyons. Masterson gave up five runs on six hits over 4.1 innings Saturday against the Cubs, marking the fourth time he's given up five runs in six turns with St. Louis.

Masterson was hit hard in the first game of a double-header with the Cubs Saturday, lasting just 4.1 innings and giving up five runs on six hits and a walk while striking out five. Three of the six hits were home runs as Masterson's struggles continue since being acquired in late-July. His spot in the rotation is definitely in jeopardy at this point and with Marco Gonzales pitching well Saturday night, and Michael Wacha nearing a return, it's possible he may have made his last start of the season for the Cardinals.

Masterson will likely pitch only from the stretch in an effort to simplify his delivery, the St. Louis Post-Dispatch reports. Masterson has a 7.43 ERA in five starts since the Cardinals acquired him in late August. He'll abandon the windup in the hopes of saving his spot in the rotation.

Masterson struggled through three innings Sunday against the Phillies, allowing five runs on six hits and two walks. Masterson struck out three on the day, but had another bad outing for the Cardinals, and now sports a 7.43 ERA with his new club through five starts.

He will try to get things rolling Sunday in Philadelphia.

Masterson (6-7) enjoyed his best start as a Cardinal, throwing seven shutout innings versus the Marlins in a 5-2 win Wednesday.

Masterson will try to keep it going Monday against the Reds.

Masterson lasted just four batters into the third inning Friday night versus the Cardinals, allowing five earned runs on seven hits and three walks while picking up a couple of strikeouts.

Masterson will be searching for bounce-back performance Wednesday in Miami.

Cardinals acquired RHP Justin Masterson from the Indians in exchange for OF James Ramsey. Masterson has struggled in his walk season, posting a 5.51 ERA over 19 starts. However, he's dealt with a knee issue and the Cards are hopeful that he'll pick things up if that injury is behind him. He should also certainly benefit from a move to the National League. Masterson will make his Cardinals' debut on Saturday against the Brewers.

Jeff Passan of Yahoo Sports reports that the Indians are "very willing to move" Justin Masterson. Passan says the Indians want "young, controllable starting pitching" in return, which is going to be a tough find. Masterson can become a free agent after the season and owns a rough 5.51 ERA and 1.63 ERA in 98 innings this year. The big right-hander is also on the disabled list currently with a right knee injury, though he's due back Friday night.
