Cubs 6, Mariners 3

MESA, Ariz. -- Here's a quick look at the Chicago Cubs' 6-3 victory over the Seattle Mariners on Friday at HoHoKam Park in the team's Cactus League home finale.

The good: Starlin Castro went out in style with a three-run go-ahead double in the seventh. Castro is hitting .351 with 15 RBIs. "I'd like to send him to Chicago right now, freeze this moment," manager Mike Quade said. "He looks like he's growing up real quick. ... I hope he continues to grow up and becomes a damn monster." Blake DeWitt went 2-for-2 with his first homer of the spring. Now officially the fourth starter, Randy Wells gave up three runs on five hits in 5 2/3 innings, striking out eight. Four relievers combined for 3 1/3 shutout innings. Marcos Mateo, a darkhorse candidate to make the roster, struck out two in the ninth to get the save.

The bad: Veteran pitcher Braden Looper retired after being informed he wasn't going to make the 25-man roster. That's about it. Oh, and third base coach Ivan DeJesus held up Tyler Colvin at third on Josh Vitter's double in the seventh on a play Colvin probably could have scored on. "[DeJesus] is learning this deal too," said his predecessor at third, Quade. The manager wasn't bothered by the hold.

Beyond the box score: Quade said he's ready for his last sleepless night as he figures out the final pitching spot. All signs point to Carlos Silva making the team, likely as the "swing guy" in the bullpen. Casey Coleman figures to return to Iowa to start. Mateo throws hard and has only given up three hits in seven one-inning appearances this spring.

Up next: Quade actually asked reporters "Who do we got first?" When a reporter thought he was talking about the Pirates' Opening Day starter, he jokingly snapped, "I'm talking about basketball! Shift gears, lady!" Quade loves the NCAA tournament. But shifting gears to baseball, Andrew Cashner (1-1) takes on C.J. Wilson and the Texas Rangers in Surprise, Ariz. on Saturday. He should find out if he's the fifth starter before the game.
