Rookie Owen Caissie slugged a two-out, two-run, walk-off homer in the ninth inning, leading the host Miami Marlins to a 4-3 win over Colorado on Sunday afternoon for a sweep of the Rockies.

Miami is 3-0 for the first time since 2009.

Victor Vodnik gave up the homer on a 94-mph changeup right down the middle.

It was the only time Miami led as Colorado had been in front since Jordan Beck’s three-run double in the first.

Deyvison De Los Santos provided another highlight for the Marlins in his major league debut. In his first plate appearance, De Los Santos slugged a 389-foot double off the glove of Brenton Doyle in center.

Colorado relievers Jimmy Herget, Antonio Senzatela and Vodnik had combined to pitch 4 1/3 scoreless innings until the game’s final pitch.

Rockies starter Jose Quintana lasted just 4 1/3 innings, allowing four hits, four walks and two runs with two strikeouts. Out of 78 pitches, only 42 were strikes.

Marlins starter Max Meyer went five innings, allowing five hits, two walks and three runs, striking out five. Out of his 81 pitches, 57 were strikes.

Colorado, with a single and a pair of walks, loaded the bases with two outs in the first. Beck then tomahawked a high sinker down the third base line for a three-run double.

Miami cut its deficit to 3-1 in the bottom of the first as Jakob Marsee walked and scored from first on a two-out, opposite-field double by Otto Lopez that one-hopped the wall in right.

The Marlins made it 3-2 in the second as Xavier Edwards singled, stole second, advanced to third on De Los Santos’ double and scored on Austin Slater’s sacrifice fly. Edwards only advanced one base on the double because it appeared that the ball would be caught.

Miami loaded the bases with two outs in the eighth, but Vodnik struck out Heriberto Hernandez on a 99.7 mph fastball that induced a check swing.

In the ninth, Edwards singled but was doubled up on a 106-mph liner by Liam Hicks to first baseman Troy Johnston, a former Marlin. Javier Sanoja followed with a double that might have been misplayed by left fielder Jake McCarthy, then Caissie followed with his second career homer on a 1-0 pitch.
