What to watch for in today's games

Cactus League features World Series rematch; Markakis makes Braves debut in Florida

Spring Training games continue today in Florida and Arizona. A rematch of the 2014 World Series is on tap in Scottsdale, Ariz., as the Braves' top free-agent acquisition makes his debut and a couple of youngsters in rotation battles take the mound.

Here are five things to watch for:

World Series rematch: KC @ SF, 4:05 p.m. ET (Listen on Gameday Audio)

The Royals and Giants played Sunday, with San Francisco taking a split squad to Surprise Stadium. They meet again today, with each sporting their full complement of players. It's the last meeting of the spring between last fall's World Series participants.

The Royals are slated to start right-hander Edinson Volquez against veteran righty Jake Peavy.

Markakis makes spring debut: ATL @ HOU, 1:05 p.m. ET (Watch on MLB.TV)

The Braves' top free-agent signing, Nick Markakis, is slated to make his Braves debut, serving as designated hitter against the Astros. Markakis has been sidelined since undergoing neck surgery in December. He still has some hurdles to clear, but he's making progress.

"He looks great and feels great, so I'm gonna DH him tomorrow," Braves manager Fredi Gonzalez said on Sunday. "If everything goes well, he'll come back here [Tuesday] and maybe play right field."

deGrom makes case for Opening Day nod: NYM @ MIA, 1:05 p.m. ET (Listen on Gameday Audio)

Mets righty Jacob deGrom, last year's National League Rookie of the Year, continues his bid to start Opening Day. He struck out six Marlins in five scoreless innings on Tuesday in his last start, retiring the last 14 batters he faced.

"I'm very pleased," deGrom said after the Mets' 6-4 win. "This week I worked on my delivery a little bit. Last time I got a little herky-jerky in the third inning, maybe trying to overthrow. I worked on just staying smooth this week, and I really felt good out there today."

Offseason trade acquisition Mat Latos starts for Miami.

Gray looks to take advantage: MIL @ COL, 4:10 p.m. ET (Listen on Gameday Audio)

The door is suddenly a bit more open for Jon Gray to make the Rockies' Opening Day rotation, following Jorge De La Rosa's groin injury and Sunday's unexpected release of Jhoulys Chacin. Gray, the Rockies' top prospect per MLB.com, has allowed three runs in nine innings and struck out seven in four appearances (one start). Monday marks his second Cactus League start.

Gonzalez continues to battle for rotation spot: CIN @ TEX, 9:05 p.m. (Watch on MLB.TV)

The Rangers are still looking to fill out their rotation, with an extra spot open following Yu Darvish's season-ending surgery. A long shot is righty Alex Gonzalez, the Rangers' No. 5 prospect per MLB.com. Gonzalez hasn't yet pitched above Double-A, but has survived the first round of cuts that sent other top pitching prospects to the Minors.

"I'm not trying to take it that way," Gonzalez said. "I hope it is, but I'm not taking it that way. I'm taking it as a game to get my work in and get ready for the season."
