The Colorado Rockies and third baseman Nolan Arenado did not reach a settlement on a one-year deal for the 2019 season on Friday, but league sources told ESPN there is a strong sense that the two sides will reach an agreement before an arbitration hearing.

Arenado, a four-time All-Star who is seen as the gem of the 2019-20 free-agent class, requested $30 million. The Rockies, meanwhile, offered $24 million. Sources told ESPN that it's likely that they will settle in the $27 million range.

At whichever amount he does settle, it will be a single-season arbitration record, breaking the mark of $23 million set by Josh Donaldson with the Toronto Blue Jays last year.

Arenado, a slick-fielding, slugging 27-year-old, is coming off a season in which he hit .297 and led the National League with 38 home runs and was second with 110 RBIs and a .935 OPS.

Meanwhile, his teammate with the Rockies, shortstop Trevor Story, was one of the many players to reach a post-deadline settlement. After originally appearing like he was headed to an arbitration hearing, Story, who made $555,000 last season, settled on a $5 million salary for 2019.

The 26-year-old Story hit .291 with 37 home runs, 108 RBIs and 27 stolen bases for the Rockies last season.

Philadelphia Phillies ace Aaron Nola, New York Yankees pitcher Luis Severino and Houston Astros teammates Gerrit Cole and Carlos Correa were among those who did not reach settlements on one-year deals for the 2019 season and are expected to head to arbitration hearings to determine their salaries.

Nola (17-6, 2.37 ERA, 224 strikeouts) and Severino (19-8, 3.39 ERA, 220 strikeouts) are both first-time-eligible starting pitchers, a market that has been notoriously difficult for players.

While first-time-eligible closers regularly exceed $6 million salaries, the only starting pitcher to do so was Dallas Keuchel coming off his Cy Young season with the Houston Astros in 2015.

Also not reaching deals Friday are Trevor Bauer, T.J. McFarland, Kyle Barraclough, Ryan Tepera, Tommy Pham, Alex Wood, Michael Fulmer, Chris Devenski and Michael Taylor.

The non-settlements capped a wild morning in which more than 100 eligible players negotiated their contracts.

There were, however, some record settlements reached Friday.

• American League MVP Mookie Betts set a new standard for players with four or more years of service by settling with the Boston Red Sox for $20 million -- a raise of $9.5 million over 2017, when he beat the Red Sox in an arbitration hearing.

• National League Cy Young Award winner Jacob deGrom more than doubled his salary with the New York Mets, jumping from $7.4 million to $17 million to set a record for the highest raise in arbitration, which had been set just hours earlier by Betts.

• Khris Davis, who led the majors with 48 home runs and was second with 123 RBIs last season, settled with the Oakland Athletics for $16.5 million -- a raise of $6 million.

Nearly 200 players are in the arbitration system, which covers every player who has spent three, four or five full seasons in the major leagues and a small percentage of those with the most service days in the class of two-year players. Once a player reaches six full seasons of service time, he can become a free agent the following winter.
