The game was scoreless through two innings of play when the River Bandits threatened to score the game's first run in the top of the third. Brett Lilley was at first with two outs when Alex Castellanos drilled a liner to left-center that bounced all the way to the wall. But as Lilley raced home, Castellanos was cut down trying to leg out a triple - and despite the Bandits' objections, plate umpire Allen Alvarez ruled that the out occurred before the runner crossed the plate.
Instead of taking a lead in the top of the third, Quad Cities watched West Michigan seize control of the game in the bottom half of the frame.
The rally started with a one-out single by a Brent Wyatt single, while a double from Douglas and a walk helped load the bases. Billy Nowlin got the Whitecaps on the board with a sacrifice fly, and the next batter drew another free pass to load the bases again. That is when Guez stepped to the plate and delivered the big blow, taking a 1-0 pitch and belting a grand slam to left-center to give West Michigan an imposing 5-0 lead.
Douglas tripled and scored to open the fifth inning, and the Whitecaps took advantage of an error in the sixth to add to their lead again. With two outs and the bases loaded, shortstop Niko Vasquez charged in to field a bouncer but his throw to first sailed high. Two unearned runs crossed the plate on the play, extending West Michigan's advantage to 8-0.
Crosby (3-0) was stifling in the win, allowing just four hits over six shutout frames and using five strikeouts to work around four walks. Relievers Erik Crichton and Tyler Conn combined to allow just one hit over the final three innings to complete the fourth shutout of the year for the Whitecaps, the league's leading pitching staff.
Adam Veres (2-2) suffered the loss for Quad Cities thanks to six runs on five hits over 4.1 innings of work, although most of the damage was done by the Guez grand slam. Kevin Thomas went the rest of the way as the piggyback starter, allowing two unearned runs on two hits over 3.2 frames.
UP NEXT: The River Bandits continue a 10-game road stretch with a 6:05 CT first pitch on Friday against the Lansing Lugnuts. Quad Cities returns to Modern Woodmen Park on June 6 to kick off an eight-game homestand, the last of the first half.
