RETURN OF THE KING

More from FoxSports

Felix Hernandez (4-4, 2.86) makes his first start for Seattle since May 27 after recovering from a right calf injury. The Mariners ace made two minor rehab appearances, most recently striking out seven over 5 2/3 innings of one-run ball with Triple-A Tacoma. He'll face the White Sox and right-hander Miguel Gonzalez (2-5, 4.40).

NEW SOX

All-Star Drew Pomeranz gets his first start with the Red Sox when Boston hosts San Francisco. The left-hander was acquired last week from San Diego for prized pitching prospect Anderson Espinoza after going 8-7 with a 2.47 ERA with the Padres. The Giants send out righty Matt Cain (1-5, 5.34).

COLON VS THE CUBS

Bartolo Colon (8-4, 3.11) and the Mets close out a three-game series with the Cubs. Colon held Chicago to two runs over six innings in a 4-3 win on July 2. He'll face right-hander Kyle Hendricks (8-6, 2.41), who hasn't lost since June 13.

COMING SOON

Blue Jays slugger Jose Bautista is expected to begin a rehab assignment and could rejoin Toronto when it opens a three-game interleague series at home against San Diego on Monday. Bautista, out since June 16 with turf toe, will begin his rehab with Class A Dunedin and then play three games with Triple-A Buffalo over the weekend. ''If all's good, you'll probably see him Monday I would guess,'' manager John Gibbons said.

KEEP IT GOING

Anthony DeSclafani was supposed to be the Reds' opening day starter until he strained an oblique late in spring training. He missed most of the first half, but is back in top-of-the-rotation form. He's 4-0 in his last five starts with a 2.67 ERA. He starts the final game of a series against the Braves.
