GOODYEAR, Ariz. -- What started as a rare Cactus League pitchers' duel ended in a slugfest on Saturday as the Indians and Royals traded long balls in a 10-run seventh inning. Cleveland prospect Francisco Mejia broke it open with a seventh-inning grand slam to lead the Indians to a 7-6 victory.
Oddly, the only run in the first six innings came with a bases-loaded walk to Kansas City's Whit Merrifield. Both teams opened up the offensive floodgates in the seventh, with the Royals sparking the onslaught with a three-run homer from designated hitter Brandon Moss.
Cleveland starter Danny Salazar was strong for four innings, striking out six while allowing two hits and a walk. In his previous three starts, Salazar pitched a total of 6 1/3 innings, allowing three runs on four hits and eight walks while striking out eight. Command was high on his priority list as he toed the rubber against the Royals.
Royals left-hander Jason Vargas, likely the No. 3 or No. 4 starter, worked through three scoreless innings. He gave up two hits, walked three and struck out three. He threw 54 pitches, 30 for strikes.

"I thought Vargy really pitched well," Royals manager Ned Yost said. "And it was nice to see Brandon Moss get that first homer. And a nice little rally in the ninth."
Both teams unleashed their pent-up offense in the seventh, with Moss's three-run shot off reliever Bryan Shaw giving the Royals a 4-0 lead.

The Tribe jumped right back into it, with Abraham Almonte sparking a rally with a leadoff single to short. He scored on a Tyler Naquin double and a throwing error from right fielder Hunter Dozier. Richie Shaffer launched his second spring dinger to make it a 4-3 game. Bobby Parnell walked three men to load the bases with two outs, and Chris Withrow entered the situation for the game's key at bat, yielding a towering fly to right that just cleared the fence for Mejia's first round-tripper of the spring.
"It was a good at-bat," Indians manager Terry Francona said of Mejia's slam. "Nobody's going to remember that in October, but it was fun to watch. He fouled off a few pitches, one was over his head, one was at his shoes. He broke a bat. He put together a pretty good at-bat. It was fun to watch us put up a crooked number like that -- I don't care who's in the game."

The Royals staged a late rally in the ninth inning, scoring two runs. With one out Cheslor Cuthbert doubled on a line drive to left field. Pinch-hitter Garin Cecchini doubled on a line drive to right field to score Cuthbert, and Billy Burns singled to bring in Cecchini. Burns stole second and went to third on a wild pitch, but Indians relieverZach McAllister struck out Dozier and Peter O'Brien to end the game.
One of Cleveland's top prospects, second baseman Mark Mathias, left the game with a dislocated left shoulder in the top of the ninth inning when he dove for Burns' grounder to second.
