Here’s an update on three key prospects at Double-A Mississippi, through Friday’s games:

Chris Ellis, RHP, 6-foot-5, 205 pounds

(Braves’ No. 14 prospect, as ranked by MLB.com)

Acquired in the offseason trade that sent Andrelton Simmons to the Angels, Ellis has appeared in seven games this season, all starts, and has yet to record a loss.

He is 5-0 with a 1.71 ERA. In 42 innings, he has allowed 26 hits, eight earned runs, 15 walks, 32 strikeouts and one home run. Opposing batters are hitting .182 against him, and he has a 0.98 WHIP.

In his most recent start, Ellis pitched seven innings May 10 and didn’t allow a run. He gave up three hits, walked one and struck out five. That was one of his three starts this season in which he allowed no runs.

Sean Newcomb, LHP, 6-5, 255

(No. 2 prospect by MLB.com)

Also acquired in the Simmons trade, Newcomb also had made seven starts, but with less success than Ellis has had. He’s 1-2 with a 3.96 ERA.

He posted two strong starts out of the gate, allowing two earned runs in 10 innings, with no decision in either game. Since those two, Newcomb is 1-2 with a 4.79 ERA.

In his past two outings he was roughed up for eight earned runs in 11 innings (6.55 ERA).

Overall, Newcomb has recorded almost a strikeout per inning (35 in 36 IP), but also has allowed 31 hits and walked 20 batters.

Dansby Swanson, SS, 6-1, 190

(No. 1 prospect by MLB.com)

Swanson is in a slump after a strong start to the season, having been held without a hit in seven of the past eight games. The exception was a 3-for-4 night May 10.

In the eight-game slump he is 3-for-28 with two runs scored and one RBI. He has six strikeouts and four walks.

He hit .333 with one homer, 12 doubles and 10 RBIs in 21 games at high-Single-A Carolina and was 5-for-8 in his first two games for the M-Braves.

In 13 games at Double-A he is hitting .250 with one homer and seven RBIs. He has a .357 on-base percentage and a .774 OPS.

One positive from his stint so far at Double-A, he has cut down on his strikeouts a bit, from once every six at-bats at Carolina to once every eight.
