PHOENIX (AP) -- Colorado Rockies manager Walt Weiss didn't realize his All-Star shortstop was hurt until he was told innings after the point.
Troy Tulowitzki was lifted because of a strained left shoulder before the third inning of the Rockies' 4-2 loss to the Arizona Diamondbacks Sunday afternoon.
Tulowitzki reached on a fielder's choice in the first inning and was attempting to score two batters later on a single by Michael Cuddyer when he slid awkwardly into home plate. Tulowitzki was easily tagged out by Miguel Montero from a throw by left fielder Jason Kubel.
"I didn't know he got hurt on the play," said Rockies manager Walt Weiss. "It sounds like he jammed his shoulder sliding into the plate."
Tulowitzki will be re-evaluated on Monday. Should he miss time, it would leave a hole in the lineup of a team that has only two wins in its last eight games after opening the season 13-4.
Colorado fell into a first-place tie with Arizona in the NL West after leading for most of the past two weeks.
"As long as you continue to go out on a day in and day out basis and play good hard baseball and continue to do the right things, it will definitely workout" said Rockies starter Jon Garland.
"We have already seen what we are able to do when we get some guys hot offensively and we are throwing the ball good. So it's not going to be a shock when we do it again and go on a nice little run."
Arizona broke through against Garland (2-2) in the third, scoring twice.
Cliff Pennington singled to right, went to second on a sacrifice and moved to third on a single to left by Gerardo Parra. After Cody Ross grounded out to advance Parra to second, Pennington scored on a passed ball charged to Wilin Rosario.
Three pitches later, Garland threw a wild pitch to score Parra for a 2-0 lead.
Paul Goldschmidt extended the lead 3-0 in the fourth when he singled and scored on Josh Wilson's double off the left-center field wall and Parra tripled to lead off the fifth and scored on a Ross single to make it 4-0.
The Rockies cut the lead in half in the sixth. Eric Young Jr. doubled for the third time in three at-bats and scored on a single to left by Dexter Fowler. Fowler later scored on a one-out wild pitch to pull Colorado to 4-2.
Colorado chased Corbin after putting runners on first and second with two outs in the seventh. But Matt Reynolds retired Young on a short popup in front of the dirt cut around home plate on the third base side to end the threat.
Garland allowed four runs -- three earned -- on eight hits with two walks, one intentional. The right-hander, who entered the game 3-3 with a 4.60 ERA against his former team, struck out two.
Arizona starter Patrick Corbin (3-0) scattered nine hits and struck out five over 6 2/3 innings. Corbin didn't walk a batter for the second straight outing and hasn't allowed a base on balls in his last 15 innings.
J.J. Putz pitched the ninth for his fifth save for the Diamondbacks.
Top Colorado prospect Nolan Arenado was called up from Triple-A Colorado Springs and went 0 for 3 with a walk while starting at third base.
The 22-year-old Arenado hit .364 with 11 doubles, three homers and 21 RBIs in 18 games for the Sky Sox. He was taken in the second round of the 2009 draft.
To make room, the Rockies designated INF Chris Nelson for assignment.
