Astros lose Lance McCullers Jr. until 2020 after Tommy John surgery

Houston Astros right-hander Lance McCullers Jr. had Tommy John surgery on Tuesday and will miss the 2019 season, the team announced.

McCullers, who went 10-6 with a 3.18 ERA in 2018, is expected to make a full recovery, the Astros said.

He was placed on the disabled list with elbow discomfort from Aug. 5 to Sept. 24 but returned during the final week of the season, making three scoreless appearances. He also made five playoff appearances, posting a 1.80 ERA.

McCullers, 25, is 29-22 in his career with a 3.67 ERA.

"Days are long but years are short," McCullers posted on Twitter. "I will be back better than ever, better believe that!!! Come back SZN starts now!!!"
