Marlins 8, Red Sox 7

JUPITER, Fla. (AP)

Christian Yelich is making the Miami Marlins think about his role this year.

The Marlins' top position prospect spoiled Jon Lester's five sharp innings, hitting a two-run homer with two outs in the ninth that lifted Miami to an 8-7 victory over the Boston Red Sox on Monday.

Yelich is hitting .375 this spring with three homers and 11 RBIs in 14 games.

''Hopefully I'm leaving a good impression, obviously,'' Yelich said. ''I have no idea what's going to happen. It's completely out of my control.''

Yelich and Miami's top overall prospect, right-hander Jose Fernandez, both came to spring training projected to start the season at Double-A.

Marlins hitting coach Tino Martinez recently said about Yelich, ''He's ready.''

Rookie manager Mike Redmond defers to his bosses when asked if Yelich could be on the opening-day roster.

''They might come down and tell me to quit playing him,'' Redmond said with a laugh. ''It's fun to get him in there. You feel like any situation he comes up he's got a chance to do something, and he hits a home run to dead center to win it.''

Even if Yelich is ready to break camp with the big league club, the Marlins may hold him back until late April to gain an extra year before he's eligible for free agency. If he was held back until about June, Miami would likely get an extra year before Yelich is eligible for arbitration.

The 21-year-old Yelich was Miami's first-round pick in 2010. The 6-foot-4, 189-pound left-handed hitter grew up in Thousand Oaks, Calif. A corner infielder in high school, he moved to the outfield in the minors and has been tabbed the Marlins' center fielder of the future.

Teammates already are giving him nicknames. Infielder Nick Green referred to Yelich as, ''The Natural'' following his walkoff homer. Outfielder Jordan Brown preferred, ''The Truth.''

Yelich's mother arrived from California last weekend to watch her son play. She has seen him homer in consecutive games - he went deep against the Atlanta Braves on Sunday before his game-winner against Boston.

''That was pretty cool - I don't really know what to say. You can't draw it up any better,'' Yelich said. ''This is the second walkoff home run in my life. The first one was a playoff game at (Class-A) Greensboro two years ago.''

What Yelich did on the game's final pitch, Boston's Jackie Bradley Jr. did on the game's first pitch: He homered off Kevin Slowey's first offering, and he reached base four times.

Bradley Jr. went 3 for 4 to raise his average to .519 (14 for 27). He added an RBI double in the fourth.

''As we get further into camp and pitchers are getting their timing down, he's still taking great swings and making good contact,'' Red Sox manager John Farrell said.

Lester allowed a first-inning run and three hits. He struck out four and retired the last 11 batters he faced.

''I feel pretty good, but I don't want to have everything clicking right now. I kind if want to build it up to that first start,'' Lester said. ''I feel good, and that's the main thing.''

Slowey gave up three runs and two hits in three innings as he fights to become Miami's fifth starter. He walked two and struck out five in his first spring start after previously throwing 6 1-3 scoreless relief innings.

Kevin Kouzmanoff's three-run double highlighted Miami's five-run seventh.
