Here’s what the MLB world is saying about Colt Emerson’s extension with the Seattle Mariners on social media:
@ByRobertMurray: BREAKING: Colt Emerson and the Seattle Mariners are in agreement on an eight-year, $95 million contract extension, sources say. The deal includes a ninth-year club option, a full no-trade clause and escalators that can bring it north of $130 million. Emerson is represented by ACES.”
@GBI News: “Thatâs serious money for a young player still early in his career. If the Marinersâ projections are right, this is a bargain. If not, that noâtrade clause will be a long, heavy anchor.”
@Yahoo Sports: “BREAKING: The Mariners are signing Colt Emerson, @MLBPipeline‘s No. 7 prospect, to an eight-year, $95 million extension worth up to $130M, per @ByRobertMurray. The deal is a record for a player who has not yet debuted in MLB.”
@NarrativeEast: “The Seattle Mariners are betting on projection over proof, locking in upside before the market prices it in. If Colt Emerson hits, this looks like a steal in 3â4 years. If he doesnât, itâs a very expensive lesson in hype vs. development. Baseball is shifting, teams are now paying for what you will be, not what youâve done.”
@SeanJoseph: “A baseball name like Colt Emerson is worth at least $50 million. I may have to rename my youngest. I don’t know that his name is strong enough. I didnât consider a future in baseball when we were picking his name, unlike Colt’s parents. They swung for the fences and connected.”
@W2truong: “what the heck I thought the Brewers deal was a lot”
@JeffPassan: “Top shortstop prospect Colt Emersonâs eight-year, $95 million contract extension with the Seattle Mariners will be done this afternoon, sources tell ESPN. Emerson will remain at Triple-A for now but is clearly a big part of Seattleâs future. First with the news: @ByRobertMurray.”
