The Texas Rangers will try to figure out a way to cool off Troy Tulowitzki in the second of two games at the Colorado Rockies on Tuesday. Tulowitzki powered the Rockies to an 8-1 win in the series opener Monday with two two-run homers, part of a remarkable run at home for the star shortstop. He is now 28-for-47 with six home runs and 21 RBIs in 17 home games, helping Colorado to a 12-5 mark at Coors Field.Nolan Arenado has been a nice complement to Tulowitzki by hitting safely in 25 straight games, the longest run in baseball this season and the second-longest in franchise history. Arenado also had a two-run homer in Monday's victory, the seventh in nine games overall for the Rockies. Texas, which is 2-2 on its current five-game road trip, fell to 4-8 all-time at Colorado.TV: 8:40 p.m. ET, FSN Southwest (Texas), ROOT (Colorado)PITCHING MATCHUP: Rangers LH Robbie Ross (1-2, 3.86 ERA) vs. Rockies RH Juan Nicasio (3-1, 4.19)Ross' fantastic first month had a rough end last Wednesday against Oakland, which got to him for 10 runs (six earned) in just 3 1/3 innings.
